Didn't mean to set up wordpress.com...switch to wordpress.org help

Ok, I just made this blog like not even 2 weeks ago...I didn't realize at the time that what I wanted was a wordpress.org and not wordpress.com....so anyways I set up wordpress.com with a domain name. But I want wordpress.org with that domain...like since its so early i don't have any content I just want to switch to .org, BUT i want that domain that I already purchased...and I don't want to deal with a $99 transfer that's really not worth it because there IS NO content thus far...IS there a way to cancel...get my 17$ back, ...just cancel my entire account then create a wordpress.org and startover.....without having to redirect and get all confusing.
